"We've not played for a while but it's nice to get some miles in the legs. Hopefully we'll come back tomorrow and improve on what we've done today.

"We've been here about a week and today was a big jump in terms of overs. We've only bowled four overs in a day so far, so to go from that to 17 or 18 each is a big jump.

"We'll take the positives from that. It's a shame we've been a bit inconsistent in our lines and lengths today, but it is something we can improve on for the rest of the trip."

Any talk of a potential bowl-off for the third seamer's place was put on hold by the WA side's batting, with Chris Lynn's 104 leading the way.

Only Boyd Rankin and Ben Stokes claimed a wicket of the potential candidates to join expected starters James Anderson and Stuart Broad - whose back problem limited him to sprint training during the tea interval.

"We're bowling as a unit, but obviously there is a place up for grabs but we are not thinking about that too much," Tremlett said.
